摘要： In a load control system as described, each of a plurality of switch circuits includes a switch electrically connected between an associated one second terminal out of a plurality of second terminals and a first terminal. A control circuit controls the switch that each of the plurality of switch circuits includes and thereby controls supply of power to a load associated with each of the plurality of switch circuits. A power supply circuit is electrically connected between the plurality of second terminals and the first terminal and receives power from a power supply via the first terminal and at least one second terminal out of the plurality of second terminals and thereby generates power to be supplied to at least the control circuit.
